2.4 List of EDB Files
SPEC_LST.dbf (Table 2) provides a complete list of all specimen sets of the test data contained in other PR-EDB files. A “set” is defined here as a group of test specimens that share the same combination of PLANT_ID, CAPSULE, HEAT_ID, and SPEC_ORI and are of the same specimen type, such as Charpy, tensile, etc. PLANT_ID + CAPSULE identify a particular experiment, and HEAT_ID + SPEC_ORI identifies a particular material. SPEC_TYPE indicates the type of specimen, and its size; for nonstandard specimens, specimen thickness can be added in front of specimen type. SPEC_POS indicates the layer(s) relative to the surface from which the specimens were cut. (This is 1/4T in most cases; 1/4T + 3/4T means that the set consists of a mixture of specimens cut from the 1/4T and 3/4T layers, and 1/4T - 3/4T means that the specimens are cut from the whole range between 1/4T and 3/4T.) If available the number of specimens in each set is listed.

12 NOTES 30 Pertinent Information Related to Data Entries, If Needed 2. SHFT_PR.dbf
SHFT_PR.dbf (Table 3) lists transition temperatures and upper-shelf energies as determined by the evaluator of the report. It lists 30 ft-lb, 50 ft-lb, and 35-mil transition temperatures (irradiated and unirradiated) and shift (difference between the two) as shown in the report and similarly lists upper- shelf energy with both absolute and relative shift values. Data describing irradiation as applied to the Charpy specimen set are also included. These data include fluences (E>1.0 MeV) and irradiation temperature at the location of the specimen, accounting for the differences within the capsule between different specimen sets. The transition temperature at 50% shear is not included since it is seldom reported and is difficult to determine reliably. It can also be readily reconstructed from the individual Charpy test data, whenever available. Also omitted are transition temperatures at other energy levels or lateral expansions such as 15 ft-lb or 3 kgm (see Table 1 for units), which are sometimes listed in older reports. Shift values listed represent the actual differences between unirradiated and irradiated data; additional safety margins that are sometimes included in reports have been subtracted. Shift values are sometimes determined in separate graphs independent from the determination of unirradiated and irradiated test data and for this reason may be inconsistent with the latter. This is indicated in the notes. Fields added for temperature and energy units allow data in different units to be entered.

RAW_C_PR.dbf (Table 4) gives a complete list of individual Charpy test results. In addition to the materials test results, the key identifiers link the raw data with the evaluations in SHFT_PR.dbf and related files. Fluence and irradiation temperature that may be different for each specimen are also included. Different sets in RAW_C_PR.dbf are contained in the associated file CV_RF_PR.dbf (Table 5). In addition to the key identifiers, CV_RF_PR.dbf includes the references for the raw Charpy data that are not included in RAW_C_PR.dbf to save space, since each specimen in the same set has the same reference. These combinations are also contained in the ASCII file RAW_C_PR.dat, used for the EDB fitting programs.

5. REAC_PR.dbf
REAC_PR.dbf (Table 7) lists fluences for E > 1.0 MeV, E > 0.1 MeV, and dpa with uncertainties, as well as fluence rates at full power, full-power-equivalent irradiation times, and startup and removal dates of the surveillance capsules. In some cases, the capsules had been moved from one reactor to another or had been irradiated more than once and annealed in between. The different irradiations are listed in separate records with the same CAPSULE identification; the sequence of irradiations is indicated in the CONFIG field. Irradiation temperatures within the capsule are reported either as maxima and minima or as a nominal (target) value, sometimes with a temperature range. Included in the temperature data is a TEMP_TAG that indicates how the irradiation temperature was determined.
Many uncertainties about capsule temperatures exist for commercial power reactors. Because these values are difficult to determine and there are some questions concerning the reported data, the Electric Power Research Institute (EPRI) has assigned seven categories that characterize the reported data and their suggested use. Category numbers are listed in the TEMP_TAG field and denote the following:
Category Description
1 Temperatures reflect the best-known capsule environment during irradiation 2 Temperatures reflect the normal cycle operating range, applicable to the capsule
during irradiation
3 Maximum temperature can be considered nominal capsule temperature 4 Minimum temperature can be considered nominal capsule temperature 5 Maximum temperature is not known or not reported
6 Minimum temperature is not known or not reported
7 No temperatures reported (listed temperatures, if any, are assumed on the basis of operating temperature or other capsules of the same reactor)

For each reactor code given in PLANT_ID, REAC_LST.dbf (Table 8) lists the full name of the reactor, utility, vendor, pressure vessel manufacturer, and the architect/engineer of the plant. No references are included since these data come from many different sources and are easily verifiable.

7. HEAT_LST.dbf
HEAT_LST.dbf (Table 9) relates the material codes given in HEAT_ID to the descriptions and heat numbers given in the reports and the MPC database. It also includes the ASTM (or foreign standard) material classification, the supplier of the material, and the thickness. The SOURCE field gives specific information about the origin of the material (if available). SCR_ap indicates that the material was obtained from excess material during fabrication of a pressure vessel (this applies also to welds);
CUTOUT, nozzle cutouts; SIM_ulated weld, if the material was not obtained from an actual weld seam but fabricated from excess plate material using the same filler and flux; and FABR_icated, the material was fabricated exclusively for irradiation experiments.

CHEM_PR.dbf (Table 10) lists the chemical compositions for the given materials together with information about the laboratory and method used, if reported, and whether it is derived from test specimens or represents generic values given by the supplier of the material. Generic values are identified in SPEC_ID as LADLE, CHECK, or HEAT, depending on what is revealed in the reports.
The term WIRE is used if the chemical composition of the filler wire, rather than that of the actual weld material, has been reported. Other terms listed in SPEC_ID are identifiers of the test specimen, the chemical composition of which was determined. All different chemical composition determinations for the same material are listed as reported, but duplications are omitted.
9. HEAT_PR.dbf
HEAT_PR.dbf (Table 11) lists up to eight different steps of heat treatment with temperature ranges, duration, quench method, and an indication of whether the particular step was intended for normalizing, austenizing, tempering, or stress relief, as far as reported. The supplier of the material and the facility performing the heat treatment, plus the identification used for the ingot (HEAT_NO) and the code used for the finished material (SUPPL_ID), are also included. Field NOMTEMP_x is the nominal temperature of the treatment step, if no MAXTEMP_x and MINTEMP_x is reported.
RANGE, if reported, indicates the deviation from the nominal temperature (in both directions if ± is attached).
